What is the maximum flow rate of this unit?

On the box it says 3 gpm but this can be confusing. While it may be able to push 3 gpm it depends on how far from the point of use you are and how hot you want the water to be. I am in a warm weather climate and find that I can use it very easily with a 1.5 gpm shower head and for use in my kitchen sink. That seems to max out the units effectiveness. Hope this helps. By the way, I am very happy with this unit.

Not sure the flow rate specs but it works fine when running on my low pump setting.

Hi Lex,I noticed the flow meter does not work very well for low flow rates. The meter was not registering when I had the flow rate set to about 1/2 gal per minute . I initial used to monitor volume of water consumed at low flow rate over two hours. The meter did not register any volume of water and the flow rate was zero. Now I water at a higher flow rate about 2 gal per minute.Maybe you can contact the Manufacture and find out minimum flow rate.

If you run it wide open, probably so.But there is a flow valve (the gray lever) that you can control the flow rate.

RVG is correct at 3 feet it is low flow. The maximum head specification is 3.9 feet. The 396 for $6 more will flow about 200gph at 3feet and has a max head of 6.3 feet.

Nope, the flow rate is different. Read here for /lots/ more info: http://www.amazon.com/review/R2B1F0JGB32PMH/ref=cm_cr_pr_viewpnt#R2B1F0JGB32PMH

The hot water that it outputs depends on the hot water that is needed. If one is taking a shower at 2 GPM, he will get 2 GPM out of the water heater, as long as the maximal heating capacity is not reached. The hotter the input water, the higher the maximum flow rate will be (up to the capacity of the pipes). The question is linked with the minimal flow rate of 0.26 GPM this unit has. Below this, the water heater shuts off.1. What happens if I need 1 GPM at 120F and that my input is at 115F. Will it shut off or will it output water above 120F ? 2. Shouldn't the minimal flow rate be expressed based on the temperature rise (0.26GPM at 50 degrees rise, 0.52 GPM at 25 degrees rise, 2.6 GPM at 5 degrees rise) ?

I measured .75gpm on the lowest flow that activates the unit. Ours is on the highest setting.

The flow is actually determined by the head of the water since the diameter of the nozzle is fixed, and the maxium velocity is determined by the head of water: v=(2gh)^0.5 I haven't checked how much head, but it must be between two or three meters.

Hi D.Lee , i run a pump 8500 LPH through the uv connected by flexible hose approx 25 mm into a solid pressure pipe that is 32 mm . The uv works well at this speed but im sure any less pressure it would work even better . The size of hose you use would depend on the amount of litres per hour pump you are using as a smaller pipe would restrict the flow . Any decent plumbing supplier will help you, no probs at all !!

The Smittybilt manual (here: http://www.smittybilt.com/docs/installation/2780.pdf) says that the max flow (i.e., at 0 PSI) is 160 liters/minute which is converted to 5.65 CFM. There is a model 2780 which has 72 LPM or 2.54 CFM which might have been copied for the incorrect flow.

I did not install a flow meter so i cannot be of any help in that regards,sorry!!!!

It certainly is greater flow rate than the replaced manual unit. I don't a have numerical GPM.

I don't know the flow rate but it is really good. We have had 2 of these over the past 10 years and they are the best shower heads around. Once you have one, you won't want anything else.

Can't say the exact flow rate but I can tell you that I love my showerhead! I like a strong stream to soothe my muscles and get through my thick hair and this does the trick.

never paid much attention to flow rate, but we have flow rate to meet our needs. I would expect that flow rate is is related to the pressure that your water supply or regulator provides.

The flow rate is 45 US get with a water column of 50cm. It claims to have a volume of 12 in: 30gph. This comes right off the box it ships in.
